Which graph represents the piecewise-defined function f(x) = StartLayout enlarged left-brace 1st Row 1st column negative x + 4, 2nd column 0 less-than-or-equal-to x less-than 3 2nd row 1st column 6, 2nd column x greater-than-or-equal-to 3 EndLayout? On a coordinate plane, a piecewise function has 2 lines. The first line has an open circle at (3, 6), continues horizontally to the left at y equals 6 with an arrow instead of an endpoint. The second line has a closed circle at (3, 0) and continues up to an open circle at (5, 3).

On a coordinate plane, a piecewise function has 2 lines. The first line has an open circle at (0, 4) and continues down to a closed circle at (3, 1). The second line has an open circle at (3, 6), continues horizontally at y = 6 with an arrow instead of an endpoint.
